Temperature monitoring system based on multiple TMP75 digital sensors and the PC's parallel port

The main purpose of this paper is to show how to build a simple temperature monitoring system by using multiple TMP75 digital sensors with 2-wire (I2C-compatible) serial interface and the PC's parallel port. The proposed system has a master-slave architecture and consists of an LPT-to-I2C adapter for the parallel port, which operates as single master, up to 8 slave modules (measurements nodes) based on the TMP75 digital sensor IC and LabVIEW application software. Such a system can be deployed across a building, laboratory or any other facility, for current environmental monitoring, or it may serve as an educational tool for students.
